摘要
在内蒙古多伦县土地利用现状的两轮调查中,利用多时相卫星图象(TM)数据,根据多伦地区各类地物的波谱特征,采用了假彩色合成及比值假彩色合成等遥感图象处理方法,建立了土地利用动态监测解译标志。在地理信息系统技术的支持下,对多伦地区土地利用的空间分布和面积进行了详细解译和测算,制作成动态遥感监测图,为多伦县地方政府提供了真实可靠的各类土地利用现状数据,为土地合理利用及沙化治理提出了相应对策。
During the twice of land use investigation in the Duolun county, Inner Mongolia Autonomous, the multitemporal satellite image data are chosen to do the image processing of false color composite and ratio false color composite based on the spectral characteristics of different land body, and the interpretation signatures of dynamic monitoring of land use are established. With the support of geographic information system, the detailed space distribution and acreage of the land use are interpreted and measured, and the dynamic monitoring map of remote sensing is made. These research results provide reliable data about the present situation of land use and scientific countermeasures for the rational utilization of land resources and prevention of the land desertification for Duolun local government.
